You can use the intervention calculator to make predictions within a certain period for a certain number of clients so that you can see the effect of a joint intervention. These effects have been calculated based on scientific research. Per target group, you can make the following calculations based on a certain number of clients and a certain period:
- Prediction of a maximum or realistic result of an intervention per category
This allows you to see, for example, how much money you save in a maximum or realistic scenario using a joint intervention for the homeless on the categories of benefits and general practitioner's visits without this including any costs for intervention.
- Prediction of total costs/benefits
Based on a 10-year period and a total costs/benefits analysis, it is possible to see in which years the investment of the intervention is break-even.
Sometimes, you know from experience that an intervention gives a result for a certain category, but research data on this are not always available. In that case, you can make an additional calculation and fill in your own values.
The intervention calculator has been made for professionals who are engaged in the rehabilitation of disadvantaged people such as: the municipalities, the central government, education sector, housing associations, energy companies, etc.
The intervention calculator works on all PCs and iPad.
The intervention calculator works in Internet Explorer, Google Chrome and Firefox.
You can use the break-even button if you set the 'show chart' button at 'total costs/benefits' and make the calculation for a period of 10 years.
The additional calculation can be made for all categories that apply to a target group, but for which no research data are available. Moreover, the research results are always shown in the additional calculation. If you do tick a category in your own calculation, but do not enter a value, this item will be set at 'zero'.
In this calculation, the result is shown without this including the costs for the intervention. If you want to make a total calculation, taking into account the costs, you opt for the total costs/benefits option. In that case, you will see the total costs, the total gross benefits, the total net benefits and the result per benefiting organisation.
No, you cannot add your own benefits.

Benefiting organisations are organisations that benefit from the rehabilitation of multi-problem clients. It not only concerns the municipality, but also educational institutions, energy companies, housing associations, insurers and the Central Government.
Insurers are both healthcare insurers, benefiting from a decrease in the use of healthcare by the clients, and insurance companies paying for material damage caused by part of the multi-problem clients (for example smashing windows).
The 'Central Government' category does not only include the government, which saves money if clients spend less time in prison for example, or if the police and courts are called in less frequently. This category also includes society as a whole, which benefits if, for example, young persons start earning better wages because they go to school for a longer period of time.
Educational institutions dealing with multi-problem clients will mostly be institutions for secondary education and middle professional education, where multi-problem young persons go to school.
Often, various benefiting organisations are already involved in joint interventions in order to help multi-problem clients find a job. By making the benefits per benefiting organisation transparent, we want to show that not only the municipality, but also many other organisations benefit from investing in counselling of multi-problem clients.
1. Break-even period/year
The break-even point, also called 'dead point' or 'critical point', is the point whereby the total benefits are equal to the total costs, and the profits therefore amount to zero. The intervention calculator calculates the break-even point based on a period of 10 years. The calculation must be based on a total costs/benefits prediction. The result is shown in a chart which indicates between which years the investment becomes profitable.
Prediction of the effects of an intervention.
Description of possible future events. It means the prediction set by the user for his output. Does the user want to see his output in a realistic form, a maximum form of both?
4. Realistic scenario
Here you can see how many euros you will most likely save with the joint intervention for the target group determined by you.
5. Maximum scenario
Here you can see how many euros you will save at most (the highest possible amount) for the target group determined by you.
6. Show chart
This means how the results must be shown. This is possible per category or per total costs/benefits (per benefiting organisation).
7. Total net benefits
These are the total proceeds minus the costs incurred.
8. Total gross benefits
These are the total proceeds from which the costs have not yet been deducted.
Interfering in a situation in order to ensure a change. It concerns an interference aimed at the rehabilitation of highly, but not impossibly, disadvantaged people.
Multi-problem people: people who have a problem in various areas of life. For example a problem with finding a job, with health, with education and with housing.
11. Chain partners
A person or organisation, outside the own organisation, making a contribution to the creation and/or delivery of the product or being involved in the product or the client as a professional. It often concerns partners of the municipality who jointly conduct an intervention aimed at the rehabilitation of disadvantaged people, such as housing associations, schools, healthcare insurers, etc.
12. Transition probabilities
This describes the probability of, for example, a homeless person returning to work, but also the probability of this person becoming unemployed again after a while.
13. Transitional probability
Has the same meaning as transition probability. For example, what is the probability of a homeless person having a roof over his head again by means of an intervention.
A meta-analysis is a research that combines studies of a certain phenomenon in order to obtain a more accurate outcome. By jointly analysing the results from previous studies, it is possible to make statements and gain insights which were impossible on the basis of each of the separate studies. A statistical re-analysis is usually conducted as well, sometimes on the basis of the source data and sometimes on the basis of already aggregated data as they were published in scientific publications on the original studies. Meta-analysis often uses statistics but is not necessarily a statistical technique. It is even possible to conduct meta-analyses on the basis of qualitative studies.
Recidivism literally means repetition. The term "recidivism" is mainly used in case of criminal offences, in other words: do people who were convicted once commit another offence? Recidivism figures show the extent to which people reoffend after a conviction.
16. Work return probability
The probability of, for example, becoming employed again within six months.
